This transducer is essentially a convection-enhanced Pirani gauge and associated electronics integrated into a single unit. It requires DC power to operate. It provides an analog output as well as two setpoint relays. It provides no direct display of pressure, but has LED indicators to show that DC power is present and to show the status of the set point relays
